HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 795, 482, 173 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 795, 482, 173 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 795, 482, 173 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 795, 482, 173 is 1.
HCF(795, 482, 173) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 795, 482, 173 is 1.
Step 1: Since 795 > 482, we apply the division lemma to 795 and 482, to get
795 = 482 x 1 + 313
Step 2: Since the reminder 482 ≠ 0, we apply division lemma to 313 and 482, to get
482 = 313 x 1 + 169
Step 3: We consider the new divisor 313 and the new remainder 169, and apply the division lemma to get
313 = 169 x 1 + 144
We consider the new divisor 169 and the new remainder 144,and apply the division lemma to get
169 = 144 x 1 + 25
We consider the new divisor 144 and the new remainder 25,and apply the division lemma to get
144 = 25 x 5 + 19
We consider the new divisor 25 and the new remainder 19,and apply the division lemma to get
25 = 19 x 1 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 795 and 482 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(25,19) = HCF(144,25) = HCF(169,144) = HCF(313,169) = HCF(482,313) = HCF(795,482) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 173 > 1, we apply the division lemma to 173 and 1, to get
173 = 1 x 173 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 173 is 1
Notice that 1 = HCF(173,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
